Answer:

Simplify 32(x^2+4x)

32x^2+128x=16(x^2+4x+3)

simplify 16(x^2+4x+3)

32x^2+128x=16x^2+64x+48

subtract 16x^2 from both sides

subtract 64x from both sides

subtract 16x^2 and 32x^2

subtract 64x from 128x

x=−2+√7,−2−√7 answer

hope this helps :))

How do you solve: 21 11/12 plus 17 5/12

GarryVolchara [31]

The problem is $21 \frac{11}{12} + 17 \frac{5}{12}$

Add the whole numbers

$21 + 17 = 38$

Match up the fractions and make sure the denominators are the same (they are)

$\frac{11}{12} + \frac{5}{12}$ $= \frac{16}{12}$

Break down the fraction

$16$ ÷ $12 = 1 \frac{4}{12}$

Reduce-You need to find a common factor for both the numerator and denominator

$4$ ÷ $4$ $= 1$

$12$ ÷ $4 = 3$

Combine everything

$38 + 1\frac{1}{3} =39 \frac{1}{3}$

Answer: $39 \frac{1}{3}$

Answer:

3) 27 cubed

4) 72 cubed

5) 125 cubed

8) 27 cubed. 3 is the length, 3 is the width, and 3 is the height.

9) 72 cubed. 6 is the length, 3 is the width, and 4 is the height.

10) 125 cubed. 5 is the length, 5 is the width, and 5 is the height.

Step-by-step explanation

Here's what to show if your teacher requires for you to show your work.

3) 3 x 3 x 3 = 27

4) 6 x 3 x 4 = 72

5) 5 x 5 x 5 = 125

8) 3 x 3 x 3 = 27

9) 6 x 3 x 4 = 72

10) 5 x 5 x 5 = 125

These are the ones I'd suggest putting the up and down form on.

10) and 5) Also put 5 x 5 = 25. 4) and 9) Also put 6 x 3 = 18.

25 18

x 5 x 4

125 72
